[18:34] anyone here familiar with audio interference caused by the ethernet cable? [18:35] after a system crash, I rebooted to find I have noise interference when I browse the internet... [18:35] _really_ annoying [18:35] I'm using a Audio 2 DJ external USB sound card... so it's a little difficult to separate them from each other [18:35] what gets me, is I didn't have this problem prior. I'm on ubuntu 10.10 with ALSA for sound [18:36] ive heard wierd things when moving a mouse before [18:36] weird* [18:36] usually with just internal cards [18:37] could it be that the USB card and the network adapter share IRQ [18:37] yeah, I'd expect internal more [18:37] cat /proc/interrupts [18:37] can I explicitly define which IRQ they use? [18:38] i think you can hack that somehow [18:38] i usually look in the bios [18:38] and if the settings arent there, i get really bored of trying to fix it ;) [18:38] its never been something i needed to worry with on a production box [18:39] detrate: you dont have the noise when the network is disabled? [18:39] I don't really know what I'm looking at here: http://pastebin.ca/2023714 [18:39] correct [18:39] if I unplug the ethernet [18:39] it's clear as day [18:39] this is with JACK running? [18:40] no, alsa [18:40] looks to me like [18:40] 44: 181517 181453 180936 181545 PCI-MSI-edge eth0 [18:40] your network is off by itself [18:40] detrate: i would say, try JACK [18:40] thats the pro level tool we have [18:41] maybe just in the spirit of trouble-shooting [18:41] how is that going to effect my other applications? [18:41] I use this machine for many thing [18:41] s [18:41] well, it wont do anything to try it [18:41] JACK is there [18:41] alright [18:41] you just run it when you want to use it [18:41] and stop it when you dont [18:41] do I need to restart or just logout to get it functional after install? [18:41] depends [18:42] not really a 'this is how to use JACK' type of thing [18:42] depends on the hardware [18:42] ah [18:42] and config [18:42] detrate: why did the system crash? [18:43] because maintainence replaced my refridgerator and apparently left the power off for over 10 minutes because my UPS can last about 10 minutes [18:43] hehe [18:43] well, i would think that is un-related then [18:43] hmmm [18:43] i would probably get a 10.04 live CD [18:44] and see if you can hear it then [18:44] try and get the installed OS out o the equation [18:44] make sure its not hardware related [18:44] and try the JACK thing [18:44] alright [18:44] and go from there [18:44] I can try the card on another computer, I know it's not the headphones / speakers [18:44] AH [18:45] yeah, that would be a good call too [18:45] I already testd them on the internal audio [18:45] and the ethernet is what's causing the interference [18:45] so weird and annoying.. [18:45] I just want to listen to nice clean music :( [18:45] no interference with the internal card? [18:45] not at all [18:45] yeah, i would do that first then [18:45] test the USB on another box [18:45] try the card on another computer? [18:46] yeah [18:46] makes sense [18:46] maybe it didnt like being shut down? [18:46] if the card is wrecked, the building manager is getting a piece of my mind [18:46] detrate: no dought [18:46] a piece of mind, and a bill ;) [19:12] yeah, it's clean on the other computer [19:12] so soundcard isn't ruined, that's good [19:13] doesn't help me understand the "software" issue though [19:13] and fwiw, I run the ethernet cable through a surge protector too [19:13] (I tested it direct and still same issue) [19:21] detrate: how about the USB on the computer? [19:21] if you boot a live CD and test it [19:21] tried every slot [19:21] no I haven't done the livecd test yet [19:21] I have to burn one first [19:21] you could take the operating system out of the loop [19:22] not sure I have one handy [19:22] its a stretch anyways [19:22] yeah, I feel like it's either config or bios at this point [19:22] maybe I should check the bios first [19:22] though, I feel like my clock would be reset if something in there changed [19:22] and i cant imagine what setting would caust that noise [19:23] from the bios settings [19:23] ifinternetisonmakenoise=1 [19:23] definitely feels like the USB power isn't "clean" [19:24] lol [19:28] omg gross, I restarted and it's ALL static now [19:28] interesting [19:28] i have a laptop like that though [19:28] the USB is borked bad [19:28] i have a little USB maudio transit [19:29] hmm [19:29] I have a usb hub I can try but I don't think that will help anything [19:29] and i screwed around with it for about 20 minutes before i went to another box [19:29] the machine came to me like that [19:29] SO i have no idea what caused it [19:29] its got other little issues here and there too === irveee is now known as irv === irv is now known as 13WAAWDNH
